SpringBoot整合ArtemisMQ筆記

本案例是springboot2.4.2整合Apache ArtemisMQ,
發送jms信息和訂閱jms消息的代碼示例

pom配置

 <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-artemis</artifactId><version>2.4.2</version></dependency>

application.yml配置

spring:artemis:mode: nativehost: localhostport: 61616user: adminpassword: admin

配置使用EnableJms注解

@EnableScheduling
@EnableJms
@SpringBootApplication
public class App {public static void main(String[] args) {SpringApplication.run(App.class, args);}
}

發送jms消息

package cn.demo.jms.send;import cn.demo.IdGenerator;
import cn.demo.TestObj;
import cn.hutool.core.util.IdUtil;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;import java.util.HashMap;
import java.util.Map;/*** jms 發送消息類型* TextMessage  字符串消息* ObjectMessage  對象消息* MapMessage  鍵值對消息* BytesMessage  字節流 消息* */
@Component
@Slf4j
public class JmsSendTxtSchedule {@Autowiredprivate JmsTemplate jmsTemplate;@Autowiredprivate IdGenerator idGenerator;@Scheduled(cron = "*/1 * * * * ?")public void t1(){//發送 字符串消息String msg = IdUtil.fastSimpleUUID()+":"+System.currentTimeMillis();log.info("t1 pre send msg:{}",msg);jmsTemplate.convertAndSend("queue.sample",msg);}@Scheduled(cron = "*/1 * * * * ?")public void t2(){//發送 對象消息TestObj obj = new TestObj();obj.setId(idGenerator.snowflakeId());obj.setTs(System.currentTimeMillis());obj.setK1(IdUtil.fastSimpleUUID());obj.setK2("t2send");log.info("t2 pre send msg:{}",obj.toString());jmsTemplate.convertAndSend("queue.testobj",obj);}@Scheduled(cron = "*/3 * * * * ?")public void  t3(){//發送 Map鍵值對消息Map<String,Object> msg = new HashMap<>();msg.put("k1","t3");msg.put("k2",System.currentTimeMillis());jmsTemplate.convertAndSend("queue.testmap",msg);}@Scheduled(cron = "*/2 * * * * ?")public void t4(){String str = "t4 --- this is a test msg"+System.currentTimeMillis();byte[] bytes = str.getBytes();//發送 字節流byte[] 消息jmsTemplate.convertAndSend("queue.testbytes",bytes);}}

訂閱jms消息

@Slf4j
@Component
public class SubQueue {@JmsListener(destination = "queue.testbytes")public void handleBytes(BytesMessage bytesMessage) throws JMSException {byte[] b = new byte[1024];int len = -1;while ((len = bytesMessage.readBytes(b)) != -1) {String s = new String(b, 0, len);log.info("訂閱到的1024字節的字符串:{}",s);}}@JmsListener(destination = "queue.testmap")public void handleMap(MapMessage map) {try {String k1 = map.getString("k1");long k2 = map.getLong("k2");log.info("監聽到queue.testmap里的鍵值對k1:{}", k1);log.info("監聽到queue.testmap里的鍵值對k2:{}", k2);} catch (JMSException e) {e.printStackTrace();}}@JmsListener(destination = "queue.sample")public void handleMessage(TextMessage message) {try {String text = message.getText();log.info("監聽到queue.sample里的信息:{}", text);} catch (JMSException e) {e.printStackTrace();}}@JmsListener(destination = "queue.testobj")public void handleObjMsg(ObjectMessage message) {try {TestObj object = (TestObj) message.getObject();log.info("監聽到queue.testobj里的信息:{}", object);} catch (JMSException e) {e.printStackTrace();log.error("ObjectMessage轉換失敗!", e);}}}
